From Publishers Weekly
Alt-cultural folk strive to save Earth from digitized doom in this novel from the prince of gonzo SF. A computer mogul's threat to replace messy reality with clean virtuality and by a memory-hungry artificial intelligence called the Big Pig propels nanotechnologist Ond Lutter, his autistic son, Chu, and their allies on an interdimensional quest for a golden harp, the Lost Chord, strung with hypertubes that can unroll the eighth dimension and unleash limitless computing power. Though he tries to unite the hard and the fuzzy sides of physics, Rucker (
Mathematicians in Love) favors the flower power of San Francisco over the number crunching of Silicon Valley. His novel vibrates with the warm rhythms of dream and imagination, not the cold logic of programming (or, for that matter, plotting). Playing with the math of quantum computing, encryption and virtual reality, Rucker places his faith in people who find true reality gnarly enough to love.

From Booklist
Always willing and able to embrace sf's trendiest themes, Rucker here takes on the volatile field of nanotechnology and the presumed inevitable "singularity" of human and computer unification. In a series of interrelated vignettes, he describes the calamity that befalls nanotech inventor Ond Lutter and his would-be benefactors when Ond unleashes a variety of self-replicating nanobots. In one episode, trillions of microscopic bots, dubbed nants, chew up Mars to create a colossal Dyson Sphere orbiting the sun. When the nants move on to Earth to transform every living being into a virtual-reality doppelganger, Ond saves the day with a nant-busting virus. The real fun begins, however, when Ond "improves" on the nants with apparently benign nanobots, called orphids, that blanket every surface and provide plugged-in users three-dimensional access to every conceivable scrap of knowledge and experience. While Rucker's improbable scenarios sometimes cross the line into pure silliness, his devoted fans and dazzled newcomers to him will revel in his willingness to push technological extrapolation to its soaring limits.
